I think light and water movement are the trick. I have about 16" haden's carpet that has maintained his color with good light and a diet of raw shrimp. I feed him every 4 or 5 days. Good luck.

stop using iodine and essential elements and do some water changes to remove all that you put in. how many lamps are in your fixture?
